/* FOCAL homepage: "Reach the homes that need you next" map-to-3D scene.
 * Pairs with /js/home-scene.js (loader), /js/home-scene-3d.js (scene) and
 * /js/home-beats.js (the copy column's beats).
 *
 * Three layouts (2026-10-07):
 *  - At rest (no JS, reduced motion, no WebGL, slow device, ?mode=still):
 *    the copy and its five beats as plain text on void, a still of the last
 *    frame, and the typeset sample record. Nothing animates or hides.
 *  - Live, desktop (1024px+ and landscape): a 100vh stage pins over a run
 *    of scroll. The copy column pins on the left and its beats take turns
 *    with the scene's stages; the record docks on the right.
 *  - Live, stacked (phones, tall tablets): the copy sits ABOVE the scene in
 *    the page and never fades out (Bryan, 10-07: a fast flick used to skip
 *    it, and re-reading meant replaying the scene). The scene pins and
 *    plays; the record follows it in the page, the leader running down
 *    into it.
 * The stacked query must match js phone(): (max-width: 1023px), (max-aspect-ratio: 9/10).
